What was found
DURING AIRCRAFT INSPECTION AN AIRCRAFT MECHANIC QUESTIONED DISCOLORING OF THE OVERRUNNING CLUTCH OUTPUT BEARING GREASE. THE BEARING DID NOT DEMONSTRATE ANY ABNORMAL PLAY OR ROUGHNESS. THE CLUTCH HAD THE CORRECT AMOUNT OF OIL INSTALLED. IT WAS DECIDED TO DISASSEMBLE THE CLUTCH ASSEMBLY. IT APPEARED THE FORWARD BEARING WAS ROTATING IN THE OUTER RACE HOUSING. UNOFFICIAL MEASUREMENT OF THE OUTER RACE HAD IT OVER LIMITS. METAL PARTICLES WERE FOUND IN THE REMAINING OIL IN THE BOTTOM OF THE OUTER RACE HOUSING. THE PART WAS REMOVED FROM SERVICE FOR FURTHER INSPECTION.
